The purpose of this bulletin is to insure the proper installation and alignment of
the FX- 850/1050 and LQ- 850/1050 push tractor assemblies.
There are two possible ways to install the tractor frame on the push tractor
assembly. If the frame is installed incorrectly, the tractor belt pins on the two
tractors will not be aligned, and the resulting printout appears to be slanted on
the page, or the perforated edge will be tom. This is caused by the marks on
the tractor shaft holders being 180 degrees ‘out of phase.’
When assembling a tractor, there are two grooves in the shaft, and two tabs
on the tractor shaft holder. lf the pins on both tractor belts are not aligned, it
will be necessary to disassemble the tractor, and rotate one tractor shaft holder
180 degrees, to bring it back into alignment with the other shaft holder.
Alignment can be verified by examining the marks in the shaft holders, which
will both be in the forward position when properly aligned, as shown in
4- 51 below.

Sound intensity is measured in units called Bels (named after Alexander Graham Bell,)
or more commonly in tenths of this fundamental unit: decibels. In making noise
measurements a weighting network is applied in an attempt to match the frequency
response of the instrument to that of the human ear. The most common is the A
weighting network, with resulting measurements expressed in dB(A).
The following is a list of current product’s noise levels tested in accordance with
standards set by the International Standards Organization (ISO). The acoustic noise
levels for the 9 pin printers are averages while printing in Near Letter Quality (NLQ)
mode using continuous paper and are not guaranteed figures. The acoustic noise
levels for the 24 pin printers are averages while printing in Letter Quality (LQ) mode
using continuous paper and are not guaranteed figures. The acoustic noise levels for
the laser printers are averages while using single sheet paper and are not guaranteed
figures.
